Trek's line of hardtails is ready to get you on the track. From the versatile Marlin, the unbeatable value of the X-Caliber, or the race ready pure-bread Superfly, you're ready to get dirty.
The bike that defined 29er mountain bikes continues to lead the charge. The Superfly lineup of crazy-light aluminum isn't just fast. It's the fastest. Be it all day adventures in the hills, 6 hour marathon events, or your local after work hours race series, Trek Superfly has you covered with stable geometry and a killer 29er set-up. If going fast is everything you're looking for, choose the 29er with the longest history at the top of the podium.
X-Caliber will get you hooked. It packs all of Trek’s XC race hardtail experience into a light, fast bike that pairs the right wheel size with each frame size. Nothing beats the efficiency, simplicity and straight-up fun of an X-Cal hardtail in 29er for the bigger or 27.5" for the 'vertically challenged' among us. Great for XC racing, or simply shredding singletrack.
